Normally death scenes are good, if you have a significant death scene and it means something it's like the audience has an attachment to you being killed that's a good thing.

One of the things that I was interested in about Moriarty was - he's so manipulative that he doesn't need to commit violence himself or kill people - he can get everyone to do what he needs to do. And sometimes they don't even know that they are being manipulated by him.

When preparing for a role, a month is a luxury. Sometimes you've maybe got two weeks before you start on something. So you have to learn how to do it quickly. And the longer you have a role, that it lives in your imagination, the more you're going to be able to contribute when you get on set. Because it's really about your subconscious having time to sit with the part, so you're out doing something and then something occurs to you, you know?

If you want to do your version, go off and write it. You bring your knowledge to it, and you can use that to shape it and color it, but it's someone else's version of that character. You're not actually playing the real person.

I never lost an argument and my parents assumed I would be a lawyer. They cast me in that role.

I keep mementos from everything I've done. I've got my cab driver's license from 'Happiness.' I've got a pair of glasses and a belt buckle from playing John Lennon. I've got a pair of sunglasses from playing Andy Warhol... It's all in a box in the garage.
